Generic shipping math for USPS, UPS, FedEx and other carrier quotes
This is not an official carrier rate engine. Instead, it helps you estimate shipping with the rates, surcharges and dimensional-weight divisor from the service you are considering. That is useful because carrier prices can depend on zone, service level, package class, account discounts and changing fuel or handling charges.
For final postage or freight purchasing, compare the estimate with the carrier’s current quote. The calculator is most useful for quick budgeting and comparing scenarios before you buy a label.
How to use this calculator
- Enter actual package weight and dimensions.
- Use the dimensional-weight divisor from the carrier or service.
- Enter the base charge and per-weight rate from your quote or rate sheet.
- Add surcharge and extra handling/insurance fees.
- Calculate billable weight, cost per package and total cost.
